Tiny living is all about intention. Every square foot, every system, every choice has to earn its place. When it comes to sanitation, traditional flush toilets often feel out of sync with the tiny home philosophy. They require water, plumbing, septic hookups, and space that many tiny homeowners simply don’t have. That’s where Sun-Mar’s GTG urine diverting composting toilet stands out as a smart, practical, and surprisingly elegant solution.
Designed with Small Spaces in Mind
The GTG toilet was built for compact living. Its footprint is small enough to fit comfortably in a tiny home bathroom without sacrificing headroom or usability. The GTG looks and functions like a conventional toilet, making it an easy transition for first-time composting toilet users. For tiny homeowners, this means no awkward layouts, no bulky tanks, and no need to redesign your interior just to accommodate a bathroom.
No Water, No Problem
One of the biggest advantages of the GTG toilet is that it’s completely waterless. In a tiny home, especially one that’s off-grid or partially off-grid, water is a precious resource. Eliminating the need for flushing can save thousands of gallons per year and significantly simplify your plumbing system.
No water also means:
- No frozen pipes in cold climates
- No leaks or costly plumbing failures
- No dependence on septic or sewer hookups
This makes the GTG ideal for tiny homes, trailers and remote properties, or anywhere infrastructure is limited.
Self-Contained and Simple
Tiny home owners value systems that are self-contained and low maintenance, and the GTG delivers on both. Sun-Mar designed the GTG to be approachable, even for people new to composting toilets. With proper ventilation and basic maintenance, it operates cleanly and odor-free. That’s a major selling point for a small space where airflow and comfort matter.
Perfect for Off-Grid and Sustainable Living
Tiny homes and sustainability often go hand in hand. The GTG toilet supports that lifestyle. By reducing water use and avoiding chemical treatments, it aligns beautifully with eco-conscious values.
For off-grid tiny homes powered by solar or designed for minimal resource use, the GTG is a natural fit. It doesn’t rely on water pressure, municipal systems, or energy-intensive processes—just smart design and natural composting principles.
Easy Installation for DIY Builders
Many tiny homes are owner-built or customized, and complicated installations can quickly become a headache. The GTG toilet keeps things refreshingly simple. With no plumbing connections required and straightforward venting, it integrates easily into new builds or retrofits.
This ease of installation saves time, money, and stress—three things every tiny homeowner appreciates.
Comfort Without Compromise
Perhaps the most overlooked aspect of composting toilets is comfort. The GTG doesn’t feel like a compromise. Seat height, usability, and everyday comfort are comparable to a standard toilet, helping tiny home residents maintain a sense of normalcy while living more sustainably.
A Smart Choice for Tiny Living
In a tiny home, every decision should support simplicity, efficiency, and sustainability. Sun-Mar’s GTG toilet checks all three boxes. It’s compact without feeling cramped, eco-friendly without being complicated, and reliable without being resource-hungry.
For anyone designing, building, or upgrading a tiny home, the GTG isn’t just a toilet. It’s a system that supports the freedom, flexibility, and intentional living that tiny homes are all about.
